ZF2 - Trigger MvcEvent::EVENT_DISPATCH_ERROR from View Controller

I am using a Restful Controller and on certain conditions, I would like the trigger the MvcEvent::EVENT_DISPATCH_ERROR and stop execution of the controller immediately after. In my Module class, I have attached an event listener for this but I can't find a way to trigger it from the view controller.

My Module code is:

public function onBootstrap(MvcEvent $mvcEvent) {
    $eventManager = $mvcEvent->getApplication()
        ->getEventManager();

    $eventManager->attach(array(MvcEvent::EVENT_DISPATCH_ERROR, MvcEvent::EVENT_RENDER_ERROR), array($this, 'error'));
}

public function error(MvcEvent $mvcEvent) {
    echo $mvcEvent->getError();
    die();
}

and my Controller code is:

public function indexAction() {
    $mvcEvent = $this->getEvent();

    $mvcEvent->setError('test-error-code');
    $mvcEvent->getTarget()->getEventManager()->trigger(MvcEvent::EVENT_DISPATCH_ERROR, $mvcEvent);
    return;
}

I think the problem is that you're not attaching to the Application's sharedEventManager. You can also use the Controller's own Event Manager to trigger the event.

Try something like this:

Module.php

public function onBootstrap(MvcEvent $mvcEvent) {

    $eventManager = $mvcEvent->getApplication()->getEventManager()->getSharedManager();

    $eventManager->attach('Zend\Stdlib\DispatchableInterface', MvcEvent::EVENT_DISPATCH_ERROR, array($this, 'error'));
}

Controller

public function indexAction() {

    $mvcEvent = $this->getEvent();
    $mvcEvent->setError('test-error-code');

    $this->getEventManager()->trigger(MvcEvent::EVENT_DISPATCH_ERROR, $mvcEvent);

    return;
}
